To all whom it may concern:

B e it known that I, ERNEs'i" L. NEWMAN, a cit1zen of the United States, residing at Parsons, in the county of Labetta and State ofKansas, have invented a new and useful Stoves ofdifferent constructions, the burner being of that type designed for using crude oil as a fuel.

" '.lfhe object of the invention is to provide a simple and inexpensive form, of burner having novel means whereby the crude oil may. spread over a broad surface and vaporized, means being utilized for catching any surplus oil discharged from the spreading means and holding it at a point where it A 'further object is to provide simple means for supplying air to the vapor in sufficient quantities to cause perfect combustion, and therefore the elimination of soot and other objectionable deposits.

A furtherpbject is to provide a heater the parts. of which can be readily separated for cleaning purposes, said heater beinginsertible into the ash-pits of stovesof different forms, and thus permitting oil to be used as a substitute for coal, wood, and similar fuels. U With these and other objectsin view the invention consists of certain novel details of construction and combinations of parts here- '35 inafter more fully described and pointed out in the claims.

-In the accompanying drawings the pre-l ferred form of the invention has been shown.

In said drawings ;-Figure l1 isv a view partly in elevation e present improvements,"the saine being shown in position within the Llower portionof a heating stove and the pipe connection between the discharge nozzle and the tanky being partly re- Y moved. Fig. 2 is a horizontal section through the mixer of the burner, the spreadingbox thereof being shown in plan. v

eferring tothe figures by characters; of.- reference 1 designates a mixing boX having.

an outlet 2 at one end opening into arspreading or fire-box 3 preferably of considerably greater area than the mixing box 1 and having an opening 4 in the top thereof which may if preferred be surrounded by an upstanding fiange 5 of asbestos or other like material. This opening is somewhat pearshaped with its small end adjacentthe o utlet 2, and arranged Within the outlet portion of the mixer 1 is a receptacle G which may .be filled with asbest-os 7.

A nozzle 8 is arranged in the top of the mixing box' and has a`valve 9 for controlling the passage of fuel therethrough, the lower end of this nozzle projecting into the upper portion of a cone frustuni 10, the lower portion of which rests upon the upper end of an inclined spreading plate 11. This plate is substantially fan-shaped and has ribs 12 upstanding therefromand diverging from the base of the cone-frustum land toward the lower o broad end of the spreading plate,

there @eng retaining flanges 13 along the edges of the plate. A recess 14 is preferably formed in the plate 11 and at the base of the cone frustum 10, this recess opening into the channels formed between the ribs l2. Said recess is located directly under the nozzle 8, sonat the fuelfdropped from said nozzle will first fall intothe recess andH Will then flow therefrom into the various channels on the spreading plate. As Jshown in Fig. 1, this plate may be supported upon Suitable brackets or standards l5 mounted upon the bottom of the mixing-box, said standards however' beingso constructed as to permit t-he circulation of air therethrough. Air inlet openings 16 are formed in the top and back of the mixing box, the air entering them being designed to fiow around the cone frustum 10 and under the spreading plate 11. It will be noted that there space between t-he lower edge of the spreading plate and the receptacle 6 through which this air may pass.

A supply tank 17 is designed t'o be supported in any suitable manner near the point of use, and this tank has a screen or filter 18 therein surrounding an outlet from which extends a supply pipe 1-9, said pipe opening into the valved nozzle 8 and being provided with a suitable check valve 20 for the purpose of preventing back pressure. The filter 18may be filled with rock salt and gum- I camphor or any other suitable material for treating the fuel so as to render `1t practi cally non-explosive.

When it is'desired to use this burner 1nconnection with a stove such, for example, as indicated at A in Fig. 1, the fire-box 3 is inserted into the base portion of the stove, the mixing box 1 being so proportionedas to completely close the opening into which the burner is inserted. After the tank 17 has been filled with crude oil the valve 9 may be opened and the oil will low downward through the filter 18 and the pipe 19 to nozzle 8, from which it will be discharged 1nto' the cone frustum 10 and the recess 14. The fuel will spread out over the plate 11 and will flow into the receptacle 6. It can here be ignited and will quickly heat the plate 11, so that the fuel as fast as it lowsover said plate will be vaporized. Any surplus fuel leaving the plate and entering the receptacle 6 will of course be consumed. Air will enter the mixing box through the opens ings 16 and will iow underthe plate 1l and around it, this air mixing thoroughly with the vapor and forming a combustible mixture. The flames produced in the box 3 will be spread out by the top of said box .and be distributed` throughout the extent `of the opening 4, these iame being directed up? wardly through the opening by the draft produced by the air entering the openings 16. Obviously practically complete combustion will be produced by spreading the fuel in the manner described and mixing it'with the air. l

Although the burner has been shownapplied to an ordinary form of heating stove, 1t is to be understood that the same can, with slight modifications, be 11s/ed in connection with cooking stoves, and can even be used in open fire-places.

The mixing box and the fire box 3 are preferably formed in one casting and the spreading plate 11, receptacle 6 and cone frustum 10 constitute the only other separate parts of the burner. It will be seen therefore that the burner can be manufacv tured lat comparatively slight cost. The

cone frustum 10 of course constitutes a hood for positively directing the fuel into the recess or cup 14 and protecting it from the action of the air current passing through the mixin box.

Obvious y various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.

What is claimed is 1. A hydro-carbon burner comprising 'a mixing box having air inlets, a lire box extending therefrom and communicating therewith, said fire box being insertible into a stove casing, there being an' opening in the top of the fire box, said top constituting spreading means, an inclined spreading plate supported within the mixing box andhaving a recess and channels extending from the recess along diverging lines to the lower end of the plate, there being side anges above the plate, a nozzle projecting into the mixing box and above and in pivotal alinement with the recess, a hollow cone frustum surrounding the nozzle and the recess and having an outlet opening, and a receptacle within the lire box and below the discharge end of the spreading plate, said receptacle having a fibrous, non-inflammable filling.
